2 Claims.

This invention relates generally to window screens and particularly towindow screen structures which include window screens arranged forvertical sliding movement with respect to the windows with which thewindow screen structures are associated, the predominant object of theinvention being to provide an improved structure of this type thatincludes elements for slidably supporting the window screens of thestructure at the windows, which elements are displaceable from theirnormal positions at the windows so that the window screens supportedthereby may be removed from said elements by being moved out ofengagement with the elements at ends thereof.

- Fig. l is an elevation of the improved structure viewing same from theinner side of a window structure with which it is associated.

In the drawings, wherein is shown, for the purpose of illustration,merely, one embodiment of the invention, A designates a window structurewhich includes a window frame B having slidably supported upper andlower window sashes C and D associated therewith. The window structureincludes the usual elements E and F for guiding the sashes duringsliding movement thereof, and in addition the lower sash D is guided bya pair of elements I disposed at opposite sides of the window structure,which constitutes parts of the improved window screen structure to whichthe invention relates.

Each of the elements I is preferably, though not necessarily, formed ofsheet metal and is shaped in cross-section as shown in Fig, 3; that isto say, each of said elements includes a wall 2 which is disposed incontact with an inner face of a vertical side wall of the window frame Band extends from the sill G of the window structure to the bottom faceof a. horizontal element H that is secured to the lower face of theupper horizontal element of the window frame. The wall 2 referred to ofeach element I is provided 55 with vertically spaced perforationsthrough Lil which screws 3 are passed for fixedly securing the element Ito the window frame. Extended at right angles from the inner end of thewall 2 of each element I is a wall 4 which is of less width than theassociated wall 2 (see Fig. 3), this wall 4 being coextensive with thewall 2 insofar as vertical length is concerned and providing a stopwhich serves as a guiding element for the lower sash D of the Windowstructure. At its forward edge the metal of the wall 2 is bentrearwardly 10 upon itself and is then bent forwardly in spaced relationwith respect to the rearwardly bent portion to provide an elongatedpocket 5 which extends throughout the vertical length of the element. Inlike manner the metal of the Wall 4 of each element I at the forwardedge of said wall is bent at a right angle with respect to said wall andthis rectangular portion is bent rearwardly and then is bent forwardlyin spaced relation with respect to said rearwardly bent portion toprovide a similar elongated pocket 6. It

is to be noted that the pockets 5 and 6 of each element I face outwardlyfrom the window sashes of the window structure.

Associated with each of the elements I is an elongated, verticallydisposed member I which includes an inner edge portion 8 that isnormally seated in the pocket 6 of the associated element I and anopposite inwardly bent edge portion 9 that is normally seated in thepocket 4 of said associated element I. Also the metal of each member 1is bent to provide a pair of spaced, inwardly extended guideways I0 andI l The members l are of approximately the same vertical length as theelements I with which they are associated and the guideways I0 and I Iopen toward each other and the guideways it) and II of each member I arealined transversely of the window structure with the guideways I0 and IIof oppositely disposed member 1. Each member I is secured to the sidewall of the window frame at its upper end by means of a long screw i2which serves as a pivot and thus permits the lower end of the member tobe swung outwardly as shown by broken lines in Fig, 2. In order to main-5 tain the members I in their normal inward positions as shown by fulllines in Fig. 2, each member 'l is provided with an aperture I3 locatedadjacent to its lower end which when the member is in its normal inwardposition registers with a similar aperture formed in the associatedelement I. These associated apertures when they are in registeredrelationship, as when the members 1 are in their inward positions,receive pins M which serve to maintain the members in such inwardpositions.

Supported for sliding movement in the transversely alined guideways ll)of the oppositely disposed members I is an upper window screen 15 andsupported for sliding movement in the transversely alined guideways llof said oppositely disposed members I is a lower window screen l6. Eachwindow screen preferably includes a sheet metal frame of suitableconstruction which supports suitable mesh material, and at the bottomedge of the upper window screen and at the upper edge of the lowerwindow screen transversely extended portions 15 and I6 of the windowscreen frames are provided which constitute meeting elements thatcontact with each other when the screensare in their normal windowscreening positions, as shown by full lines in Fig. 2, and thus. closethe space between the screens. Also each screen is provided with afinger piece I! preferably in the form of a loop which facilitates theoperation of sliding said screens through their guideways.

When in the use of the improved window screen structure disclosed hereinit is desired to remove the screens i5 and I6 from their guideways inwhich they are slidablysupported, it is necessary, merely, to remove thepins I 4 and move the pivoted members 1 outwardly at their lower ends tothe position shown by broken lines in Fig. 2. This withdraws theportions 8 and 9 of the members I from the pockets 5 and 6 of theelements I as shown in Fig. 6. The screens may then be moved downwardlyof their guideways and out of said guideways at the lower ends thereof,after which the members 1 are returned to their normal inward positionsand the pins I4 are replaced for maintaining the members in such inwardpositions. The window screens l5 and I6 may be introduced into theguideways of the members i in the same manner.

In order to provide for the window screens being maintained stationaryin any positions to which they may be adjusted with respect to theguideways l0 and II, I secure to the side portions of the frames of saidwindow screens friction elements i8 which are of substantially U- shapedformation as shown to the best advantage in Fig. 5, These frictionelements embrace the frames of the window screens, the inner legs of thefriction elements being secured in any suitable manner to the windowscreen frames and the outer legs being free and constituting resilientfingers which contact closely with walls of the guideways so astoproduce friction. Be-

cause of this arrangement the window screens may be raised or lowered toany desired positions and the resilient friction producing fingers ofthe elements I8 will maintain the window screens in such positions.

When the members i are in their normal posi tions as shown in Fig. 3,said members are braced and rendered rigid by having their portions 8and 9 seated in the pockets 5 and 6 of the elements I. Furthermore theparticular manner of assembling the associated elements I and 1 providesfor a smooth, neat appearing structure which adds to the appearance of awindow structure. Additionally the fact that the portions 8 and 9 of themembers 1 substantially fill the pockets 4 and 6 prevents dirt and dustfrom lodging in said pockets.

While the improved window is by preference arranged at window structureas shown in the drawings, it is obvious that said structure may, ifdesired, be used at the outside of window structures.
